Compiling under Linux, Bag of fun! Options

[iprice]

Hi,

Noticed a bit of discussion about the Linux compilation was in the other thread but thought it might be better to break this out.... I'm fairly dedicated to geting this thing (re)built under linux, and heres my story so far...

A couple of months ago I setup a 'training comm etc' server on my home Linux box, 12 bots and a few player slots for commander / etc.

Compiling RCBot was rather difficult, I was using "gcc version 3.3 20030226 (prerelease) (SuSE Linux)" as the compiler and had to make various modifications to the sources to get it to compile.

Please note while I am a programmer I am *not* a C++ programmer (never liked the language, but something I always felt I needed overcome perhaps one day). One of the things I hate about the C strain is the error messages from most compilers are horrendous.

Anyway lets not get into the old programming language holy wars, just wanted to point out I have very little idea specifically what i'm doing, but a sound backgound in programming and Unix and so forth.

I found the 'linux binaries' supplied would just crash randomly, particularly on bot add's as detailed in various forums, which is what got me working on the source.

I made the following changes to the rcbot source distribution to get it to compile under linux and run successfully - the only issue apart from the AI being a bit poor in places (like skulks at your bot's feet dont get seen usually , rines obsessed with rushing and knifing OCs etc) was the max_paths_revs falling to 0 after a while, which isn't too bad and something i'd schedule a cronjob/rcon to fix quite easily.
*) The addition of "-I ." to the makefile parameters to include the current directory in the include search
*) The addition of the "-fpermissive" flag to the makefile to ignore errors regarding ISO C++ standards violation, variables declared with no type (?) etc
*) Then things got wierd, I get errors like

oK, well, I thought i'd touch back in here, just incase anyone was wondering about my progress

I got the 'linuxified' source code, but still had issues compiling the code (the "expected ; before 'it'" error, which means so little to me)

I downloaded GCC 3.3.6 and compiled this (and omg it wouldn't compile... i actually had to modify the sources for the C compiler to get it to compile under GCC 3.4)... Anyway this actually fixes the error, so stick with GCC 3.3.6 rather than 3.4.4 unless you actually know something about GC(C++) error messages

Just gone back to my server however after running the bots for a couple of days to find the machine pretty much dead on its feet... The HLDS server has grown to consume over 1.5GB of ram IIRC, was there a memory leak in older versions of RCBot?

Which leads me to wonder what else has changed in the source code since the version i'm compiling... Are there any ways of tracking versions of the code, generating 'diff's of the changes which I could try apply to the source... or getting the unmodified version of the RCBot sources for the version the linux code is based on (so i can see /those/ diffs and reapply to the latest greatest rcbot code)?

I did notice the other thread about CVS, so perhaps none of this is in place yet?

Anyway, got it working again, where to go from here to keep it 'up to date' with the latest developments?

Thanks,
Iain
